National Incident-Based Reporting System, 2002 (ICPSR 4066)

Principal Investigator(s):United States Department of Justice. Federal Bureau of Investigation

Summary:

The National Incident-Based Reporting System (NIBRS) is a
part of the Uniform Crime Reporting Program (UCR), administered by the
Federal Bureau of Investigation (FBI). In the late 1970s, the law
enforcement community called for a thorough evaluative study of the
UCR with the objective of recommending an expanded and enhanced UCR
program to meet law enforcement needs into the 21st century. The FBI
fully concurred with the need for an updated program to meet

The National Incident-Based Reporting System (NIBRS) is a
part of the Uniform Crime Reporting Program (UCR), administered by the
Federal Bureau of Investigation (FBI). In the late 1970s, the law
enforcement community called for a thorough evaluative study of the
UCR with the objective of recommending an expanded and enhanced UCR
program to meet law enforcement needs into the 21st century. The FBI
fully concurred with the need for an updated program to meet
contemporary needs and provided its support, formulating a
comprehensive redesign effort. Following a multiyear study, a
"Blueprint for the Future of the Uniform Crime Reporting Program" was
developed. Using the "Blueprint" and in consultation with local and
state law enforcement executives, the FBI formulated new guidelines
for the Uniform Crime Reports. The National Incident-Based Reporting
System (NIBRS) is being implemented to meet these guidelines. NIBRS
data are archived at ICPSR as 13 separate data files per year, which
may be merged by using linkage variables. The data focus on a variety
of aspects of a crime incident. Part 4, Administrative Segment, offers
data on the incident itself (date and time). Each crime incident is
delineated by one administrative segment record. Also provided are
Part 5, Offense Segment (offense type, location, weapon use, and bias
motivation), Part 6, Property Segment (type of property loss, property
description, property value, drug type and quantity), Part 7, Victim
Segment (age, sex, race, ethnicity, and injuries), Part 8, Offender
Segment (age, sex, and race), and Part 9, Arrestee Segment (arrest
date, age, sex, race, and weapon use). The Batch Header Segment (Parts
1-3) separates and identifies individual police agencies by
Originating Agency Identifier (ORI). Batch Header information, which
is contained on three records for each ORI, includes agency name,
geographic location, and population of the area. Part 10, Group B
Arrest Report Segment, includes arrestee data for Group B crimes.
Window Segments files (Parts 11-13) pertain to incidents for which the
complete Group A Incident Report was not submitted to the FBI. In
general, a Window Segment record will be generated if the incident
occurred prior to January 1 of the previous year or if the incident
occurred prior to when the agency started NIBRS reporting. As with
UCR, participation in NIBRS is voluntary on the part of law
enforcement agencies. The data are not a representative sample of
crime in the United States. For 2002, 23 states, fully or partially
participating in NIBRS, were included in the dataset.

Extent of Processing: ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of
disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major
statistical software formats as well as standard codebooks to accompany the data. In addition to
these procedures, ICPSR performed the following processing steps for this data collection:

Created online analysis version with question text.

Checked for undocumented or out-of-range codes.

Original ICPSR Release:2004-10-18

Version History:

2007-03-15 The dataset was updated to remove
duplicate records.

2006-03-30 File CB4066.ALL.PDF was removed from any
previous datasets and flagged as a study-level file, so that it will
accompany all downloads.

one or more datasets. These files included additional setup files as
well as one or more of the following: SAS program, SAS transport, SPSS
